SHOE-HOLDING JACK FORSHOE-NAILING MACHINES.

SPECIFICATION forming part of Letters Patent No. 611,991, dated October 4, 1898. I

Application filed July 14, 1897. Serial No. 644,550. (No model.)

To all whom it may concern:

Be it known that I, LOUIS A. CASGRAIN, of Winchester, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Shoe-Holding Heads for-Nail in g-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the production of a novel, simple, and efiicient shoeholding jack, it being adapted more especially for holding shoes having what are called spring heels, the apparatus being used when attaching the sole and heel to the upper; but the machine may be used when nailing any usual thin heels to the sole and shoe.

The jack is adapted to support a last, and the last-pin is so mounted that it, with the last, may be turned more or less aboutavertical axis, and in so turning the last-pin and last the angular position or location of the bottom of the last with relation to a horizontal plane maybe varied as required. The last-pin may also be so supported that it may move not only vertically, but also somewhat laterally, the lateral movement of the last-pin aiding in crowding the top of the toe of the last into and upon a suitable toe rest or support.

The last-pin is carried above the usual horn shaft or spindle by or through a universal or gimbal jointed connection, shown as a main and an auxiliary yoke.

Figure l, in side elevation, shows a sufficient portion of a jack containing my improvements to enable myinvention to be understood, the jack havingja last and shoe mounted upon it in operative position. Fig. 2 is a right-hand side elevation of Fig. l-with the last andshoeremoved. Fig. 3 is a detail showing the forked slide in which is pivotally mounted the last-pin. Fig. 4 shows the locking block or device detached. Fig. 5 shows a modified form of last-pin and its collar and part of the support or auxiliary yoke upon which it will be mounted. Referring to the drawings, A represents the upper end of any usualhorn shaft or post common to usual nailing-machines, and B is part of the usual nose-piece to rest upon the work at the point whereithe nail is being driven into it, said nose-piece having a suitable opening, as I), through which a nail may be driven into the shoe. In Fig. 1, by full lines, the bottom of this nose-piece is made flat; but it may present a beveled under side, if desired, as shown by dotted lines in Fig. 1, that depending upon the particular work to be done. I

The upper end of the horn shaft or post has secured to it by a suitable screw 0 the split hub of a main yoke 0 said yoke at its lower end having suitable pivots, shown as stud-screws 0?, which enter and serve as pivots for a ringD. This ring has pivoted to it loosely, as by stud-screws D, an auxiliary yoke D provided at its upper end with a hole (I, which is bored therethrough at an angle With relation to the center of said horn-shaft.

The ring D is provided with suitable stops, as D which as the auxiliary yoke D turns in one or the other direction about the studscrews D meet the yoke, the stops thereby limiting the extent of movement of the said auxiliary yoke D on or with relation to the tipping ring D.

The diagonally-bored hole d of the auxiliary yoke receives a collared sleeve d,which is also bored diagonally or angularly, as at 61 with relation to the center of said sleeve, said diagonal bore receiving, it may be, the Shank d of a forked slide d, the lower end of said shank having fixed to it by a suitable screw a Washer or plate at, which under the action Ofjt spring 6, surrounding the upper end of the said sleeve and acting against the shoulder of the forked slide, prevents theshank d from being lifted from the sleeve when the shoe is not acted upon by the nose-piece, the rotation of the sleeve d in the yoke varying the angularity of the last-pin.

Thenarrow neck 6 of the forked slide d is embraced by a U-shaped locking block or device 6 (shown in Fig. 4,) the top of which is represented as concave and provided with a series of teeth.

The forked slide in the drawings, Figs. 1 to 3, has holes in its upper ends to receive a pin or stud f, said pin also passing through holes in the inner end of a lever e and through a slot (shown by dotted lines, Fig. 1) in the shank f of thelast-pin f said shank entering a slot in the inner end of said lever 6 The lower end of the shank of the said last-pin has (see Fig. 1) a notch f which is entered by a strut or pin J, the opposite end of which rests against the bottom or shoulder f of the slot cutin the end of the lever 6 The lever c has, as shown, a plurality of open hubs e either of which may receive a rod it, provided at its upper end with a toerest h, and said rod may be put into either one of said open hubs and be there secured fixedly by a set-screw 7L2, and in either of the adjustments of said rod the toe-rest, preparatory to fixing it in position, maybe made to point either to the right or to the left, as may be desired, thereby greatly increasing the range of adjustment of the said toe-rest to lasts and shoes of different lengths. Pressure on the fore part of the last transmitted through the toe-rest and the lever 6 causes the strut or pin f to act on the shank of the last-pin, turning the last-pin, so that the closeness of the contact of the upper on the last with the toe-rest is augmented.

The lever c has a segmental surface f provided with teeth, and when the last-pin and said lever are depressed, as when the upward pressure of the horn-shaft is operating to force the sole or heel of the shoe against the nose-piece, the teeth on the segmental part f of the lever 6 meet and engage the locking device 6 thereby temporarily locking the said lever in place and holding the shoe at the desired or necessary inclination.

In the operation of driving the nails into the shoe, heel, or sole the horn-shaft is lowered after each nail is driven to thereby enable the usual feeding means to engage and move the shoe the proper distance to receive another nail, and, if necessary, the operator at any time when the horn-shaft is depressed for feeding may engage the lever e by hand and turn the same to change the inclination of the last-pin, and as the horn-shaft rises preparatory to the driving of another nail the locking device will engage the segmental toothed portion of the lever e and again hold said lever in a fixed position with the heel or sole at the proper inclination. This provision of adjusting the inclination of the last-pin is essential in orderthat the nail being driven may always be inserted at the proper angle into the heel or sole no matter what may be the particular inclination or contour of the heel or sole.

As a modification the last-pin h (see Fig. 5) may be inserted directly into the diagonallybored hole of the collar al the said collar whenever the clamping-screw e is unloosened being turned, thus changing the last-pinas to its inclination from a vertical plane, as may be desired.

Ilaving fully described my invention, What I claim, and desire to secure by Letters Patent, is-- 1. In a nailing-machine, a last-holding pin, a diagonally-bored sleeve to receive said pin, and means to support said sleeve so that it may be rotated to vary the inclination of said pin in said support more or less out of a vertical position, substantially as described.
